Abstract
A chemical kinetic model was developed for a multicomponent gasoline surrogate consisting of Tetrahydrofuran (THF), iso-octane, n-heptane, and toluene, covering some cross-reactions. The mechanism included 1954 species and 7908 reactions. It was verified that the outcomes agreed with the experimental observations of each pure component and its diverse mixtures. The surrogates perform better in forecasting experimental values due to the THF. The impact of cross-reactions was discussed about the ignition delays. The research found two cross-reactions, one between alkyl peroxyl radicals and pure components and one between benzyl peroxyl radicals and pure components (Types 2 and 3, respectively). Of these, Type 2 affected deceleration, and Type 3 on acceleration. Cross-reactions could increase the sensitivity coefficient for OH sensitivity analysis, promoting CH3 and O2 to produce HCHO. Combined with PSR species profiles, olefins, CO, and HCHO were the main products of oxidation. However, SENKIN and PREMIX simulations did not find the effect of cross-reactions within the intermediates.
